Application filed July 25,

My invention relates to driers and; the principal object of my invention is to prov de a new ancl improved device of this type. in the drawings accompanying this specification and forming a part of this application I have shown, for purposes of illustration, one form which my invention may assume. in these rlrawings:

Figure l is a general view of this illustrative emhofiiment of my invention,

Figure 2 is a horizontal section taken on the line 22 of Figure l, and enlarged, while Figure 3 is a diagrammatic representation of the electrical system.

The embodiment of my invention herein shown comprises a fan 11 secure l to one encl oi? the shaft 12 of a motor 13 which carries at its forward enii a heater 14 ancl a lamp socket 15 both supportecl upon an insulatinp; base 16 carriecl by two arms 17 extending outwanlly from lugs 18 formed on the housing 19 of the motor 13, the entire fan-motor-heater-soclret unit being supportecl from a supporting ring 20 by nieans of radial ribs 21 extending between the motor housing 19 and the supporting ring 20. lFhe entire unit is encloseu by a pair of easing sections 22 and 23 which overlie reiuoecl shoul'iers 2i an. 25 tormecl respectively on the rear and forward sides of the supporting ring 20, and are securecl to the ring 29 in any suitable manner, as by set screws 26 e2:- tenclin through the casing sections 22 and 23 into the rerluce. shoulders 24 and 25 respectively, and the supporting ring 20, ancl the entire unit. carried thereby including" the casing sections 22 ancl23, are supported by means of bracket 2? integral with the supporting ring}; 20 anti itseli provided with a circular pro ection 28 edaptecl to he helcl by means of a bolt 29 in cooperating pivotal relation to similar circular projection 3t) carried by a block 31 pi'oviiletl with a pin 32 arranged to he rotatably receivecl by an suitable socket, such as the recess 33 exten ing downwardly into the top of a shank 3e itself arranged to be receivecl within the bore of a stem 35 which is provirlecl with a screw 38 to lock the shank 3 in adjusted position and is itself supported from a base 3'? having a central annular portion 38 pro violecl aireoess 39 for the reception of the lower encl of the stem 35, having 192%. Serial No. 125,271. E a q screw 40 to hold the stem 35 in position in the base 3'2 anol provided with three legs ll each provided with a roller or caster 42.

The casing section 22 is proviclecl with an inlet opening; 43 closed by means of a wire screen it, the casing section 23 is provided with an outlet opening 45, the socket 15 is provided with a lamp 46, and with a reflector 4C7 olirecting the lightand heat from the lamp to through the outlet opening 45, ancl the various parts of the drier, including the fan ll, anti the casing sections 22 and 23, encl the ribs 21, and the motor casing 13, ancl the heater 14, aml the reflector 17, and the opening 4-5, are all so formed and proportionecl and positioned thatthe air drawn in by the fan 11 through the opening 43 in the casing; section 22 is given a rotating or swirling motion which is permittetl to persist throughout-the entire length of the easing 23 so that the air emerges through the opening 45 still swirling and only at the periphery of the opening 45, and there is produced a secondary air current flowing into the opening 45 through the center of the swirl drawn in by the suction produce by the swirl itself.

@perating; power for the entire unit is proyicletl through a pair of line wires 48 and 49 connected to a main switch 50 providetl with a first terminal 51 receiving the line wire es, and with a second terminal 52 receiving the line wire 49, connected by means of a conductor 59 to a switch 60 in. turn connecteci by a coneluctor 61 to one terminal of the lamp l5, and also connected. by means of a conductor 53 to a switch arm 54: having three operating positions in the first of which engages a blank contact 55, in the seoonol of which it engages a terminal 62 connected by means eta conductor 63 to one terminal ofthe motor 13, and in the third of which it engages a first terminal 66 connectecl by means of a conductor 67 to the terminal 62, ancl'a second terminal 64 connected by means of a conductor 57 to one terminal of the heater 14:, the other terminal of the heater: l4 and the other terminal of the lamp 15 being connected-L by branch conductors 68 and 69 to a sub-conductor 70, the other torminsl of the motor 13 being connected by means of a conductor 71 to a resistance 72 having its second terminal connecterl to a sub-conductor 73, the two sub-conductors SUE ltlll lltl lid

tlll

l0 and 78 being connected by means of a conductor 74- to the terminal 51 of the switch to;

romthe above description it will be understood by those skilled in the art that by placing the switch in the second position ll energize the motor 13 and fan 11 without energization oi the heater it, and that with the switch 50 in the third position ll energize both the motor 13 and tan 1]., and also the heater 1t, and that the lamp 115 may be energized at any time independently of the energization of either the motor 13 or the heater 14, and depending only on the position of the switch 60.

Under these circumstances those "familiar with driers of this type, and with the use thereof, for drying hair, will a preciate that l can secure the operation ct any of the three devices, or any combination or the three devices, likely to be desired for that purpose, and also that by virtue of the air currents set up by the embodiment of my invention herein shown and described ll can produce an air current which flows from the drier in a gentle expanding stream flowing outwardly about the head and then returning through the hair itself to supply the air drawn in through the center out the swirl.

Under these circumstances those skilled in the art will appreciate that l have produced a new and improved drier,

At the same time those skilled in the art will realise that the particular embodiment or" my invention herein shown and described may be variously changed and modified without departing "from the spirit of my invention or sacrificing the advantages thereof and it will therefore be understood that the,

disclosure herein is illustrative only and that my invention is not limited thereto,
